FEATURES
DESCRIPTION

•
Unity Gain Bandwidth: 1.8 GHz
•
High Slew Rate: 6700 V/µs (G = 2 V/V,
RL = 100 Ω, 5-V Step)
The THS3201 is
a
wide-band, high-speed
current-feedback amplifier, designed to operate over
a wide supply range of ±3.3 V to ±7.5 V for today's
high-performance applications.

•
IMD3: –78 dBc at 20 MHz: (G = 10 V/V,
RL = 100 Ω, 2-VPP Envelope)
The wide supply range, combined with low distortion
and high slew rate, makes the THS3201 ideally
suited for arbitrary waveform driver applications. The
Noise Figure: 11 dB (G = 10 V/V, RG = 28 Ω,
RF = 255 Ω)

Voltage Noise: 1.65 nV/√Hz
high-resolution and high-sampling rate ADCs.
Noninverting Current Noise: 13.4 pA/√Hz
Inverting Current Noise: 20 pA/√Hz
High-voltage operation capabilties make the
THS3201 especially suitable for many test,
measurement, and ATE
applications
where

Output Drive: 100 mA
lower-voltage devices do not offer enough voltage
swing capabilty. Output rise and fall times are nearly
independent of step size (to first-order appoximation),
making the THS3201 ideal for buffering small to large
step pulses with excellent linearity in high dynamic
systems.
Power-Supply Voltage Range: ±3.3 V to ±7.5 V
SUPPORTS DEFENSE, AEROSPACE,
